[PATCH v2 02/10] block: set bip_vcnt correctly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Set the bip_vcnt correctly in bio_integrity_init_user and
bio_integrity_copy_user. If the bio gets split at a later point,
this value is required to set the right bip_vcnt in the cloned bio.
